Application filed May 15, 1913. Serial No. 767,838.

T 0 all whom it may concern Be it known that 1, WILLIAM H. GoLDINc, acitizen of the United States, residing at Franklin, in the county ofNorfolk and State of lvlassachusetts, have invented certain new anduseful improvements in Inking Apparatus for Printing-Presses, of whichthe following is a specification, reference being had therein to theaccompanying drawing.

this invention relates to certain new and useful improvements in inkingapparatus for printing presses; the object of the invention being toprovide novel means for operating the ink disk, whereby the same can beadjusted in accordance with the speed of the press in order to regulatethe distri bution of the ink.

Another object of the invention is to provide novel means foroscillating the ink disk which is so constructed that the same isoscillated by the roller carrying frame through the medium of a leverhaving an operable connection with a member mounted upon the bearingspindle of the disk; said member carrying a pawl co-acting with acircular rack formed on the under face of the disk.

A still further object of the invention is to provide a roller framewith vibrating form rollers in which the upper and lower rolls are setat an angle from the center roll, whereby the upper roll will graduallymove to the right and the lower to the left and vice versa in themovement of the roller carrying frame, in order to distribute the ink ina uniform thickness over the form of the press.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawingsFigure 1, is a side elevation of a portion of a pressshowing the application of my improved inking apparatus; Fig. 2, is afront elevation; the inking disk being partly broken away in order toshow the operating mechanism for oscillating the disk; Fig. 8, is aninverted plan of the arm for oscillating the disk; Fig. 4., in anelevation of the same; Fig. 5, is a side View of the operating lever;Fig. 6, is an edge view of the same; and Fig. 7, is a detail view of theadjusting pin.

Like numerals of reference refer to like parts in the several figures ofthe drawings.

in the drawings, 1 indicates a portion of the frame of a printing press,2 the roller carrying frame pivotally mounted thereon and adapted to beoscillated by a link 3 in the ordinary manner; said frame being composedof side members connected together by a back tie which is provided witha slotted arm 5 in which is adjustably mounted a pin 6 locked in itsadjusted postion by a machine bolt 7 working in a threaded bore formedin one end thereof. The purpose of this pin will be hereinafter fullydescribed.

The roller frame 2 is provided with a plurality of spring-actuated rods8 having hooked outer ends 9 in which are mounted suitable bearingsleeves l0. Mounted in the bearing sleeves 10 are the supportingspindles ll of form rollers l2, l3 and it; said spindles being free torotate and slide within the bearing sleeves for the purpose hereinafterfully described.

The frame 1 of the press is provided with a type bed 15 over which theform rollers 12, 13 and 14: are adapted to travel back and forth in theordinary manner, and the spring-actuated rods are set within the frame 2in such a manner that the rollers 12 and 14: are set at an angle inrespect to the central roller 13 in order to cause the rollers 12 and 1%to vibrate back and forth in the movement of the rollers over the typebed. When the frame is in the upper position and starts downwardly overthe type bed, the upper roller gradually moves to the right and thelower roller to the left, whereby the distribution of ink over the formis greatly improved, it of course being understood that in the reversemovement of the roller frame, the distributing rollers move in oppositedirections.

It will be seen from the above construction, that the manner ofoperating the roller carrying frame has not been changed in anymannerfrom the ordinary form of press now in use, but I have found that bysetting the form rollers at an angle, a great advantage is obtained indistributing the ink over the form.

Projecting upwardly from the frame 1 of the press, is a standard 16having a supporting arm 17 extending therefrom which is provided with abearing 18 in which a spindle 19 of an ink disk 20 is pivotally mounted;said disk being provided with a circular rack 20' upon its under face,as clearly shown in Fig. 1. The lower portion of the bearing 18 of thearm 17 is bifurcated to receive one of the furcations of the bifurcatedarm 21 which is pivotally mounted upon the spindle 19 of the disk 20 andheld in position thereby in order that the same is free to oscillateupon the spindle under the disk. The other end of the arm 21 is providedwith an upwardly projecting bifurcated portion 22 in which is pivotallymounted a gravity pawl 23 co-acting with the rack 21 in such a mannerthat when the arm is moved in one position, the disk will be oscillatedand when moved in a reverse direction, the pawl will ride over the teethof the rack in order to obtain the intermittent motion which is commonin disks LOW in use on printing presses.

lhe arm 21 is provided with a lateral projection 24 extending to therear of the center of the disk and is provided with teeth 25 upon itsunder face forming a segment which co-acts with teeth 26 formed on theupper end of a pivoted lever 27 mounted upon the standard 16 as shown at28; the lower end of said lever being engaged by the pin 6 of the arm 5in such a manner that the same will be oscillated by the movement of theroller carrying frame. The lever 27 is provided with a pin 29 whichco-acts with a stop 30 arranged on the standard in order to limit theswinging movement of the lever in one direction. By adjusting the pin 6within the slotted arm 5, the speed of the oscillation of the ink disk21 can be regulated according to the speed of the press in order toregulate the distribution of the ink.

From the foregoing description, it will be seen that I have provided aprinting press in which the rotary movement of the inking disk can beadjusted according to the speed of the press by shifting the pin inorder to adjust the point of contact between the-pin and the operatinglever, whereby the speed of the inking disk will be increased ordecreased.

lt will also be seen that I have provided novel means for vibrating theform rollers as they move over the form by arranging the same at anangle to a central roller.
